Ah, but that's the thing.
Clearly, these guys look like a consciously synergistic team. But once one goes down, the remaining two becomes exponentially easier to take out.
Take the mass buffer, the mooks become just annoying Qi batteries and we can throw down with the other two, who look like a disabled and a blaster.
Most importantly perhaps, reinforcements have stopped, we are nearly fully buffed up (I think Ten Rings is missing?), full health and certainly full Qi.
Their horde didn't whittle us down. It recouped our set up cost, instead.
Three creepy greens are no laughing matter. But neither is a fully buffed Ling Qi, in the dark, with a horde to drain Qi from.
